Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0023] The present invention aims at the problem that the infrared sensor below the terminal display screen in the prior art causes abnormal display and uneven display on the terminal display screen, and provides an infrared sensor structure, such as figure 2 shown, including:
[0024] a substrate 4 and an isolation cover 5 arranged on the substrate 4;
[0025] Wherein, the substrate 4 and the isolation cover 5 jointly form a first accommodating spac...

The invention provides an infrared sensor structure, a display screen structure and a terminal. The infrared sensor structure comprises a substrate and an isolation cover arranged on the substrate; Wherein the substrate and the isolation cover form a first accommodating space and a second accommodating space together; An infrared emitter fixed on the substrate is arranged in the first accommodating space, and an infrared photosensitive unit fixed on the substrate is arranged in the second accommodating space; And the wavelength lower limit value of the working wave band of the infrared photosensitive unit is greater than 1100 nm. According to the scheme, when the infrared sensor structure is arranged under the screen, the Oled screen TFT driving layer made of the Si material can be prevented from being excited, and the problems of abnormal screen display and non-uniform display caused by traditional infrared placement under the screen can be solved.
Description
technical field [0001] The invention relates to the technical field of terminals, in particular to an infrared sensor structure, a display screen structure and a terminal. Background technique [0002] With the rapid development of smart phones, full-screen design has become the mainstream in the future. On the front of the smartphone, an infrared sensor is usually placed to detect the user's approaching action, so as to intelligently turn off the screen during a call to prevent the face from accidentally touching the phone and hanging up. Traditional infrared sensors are usually placed on the frame outside the screen (such as figure 1 As shown, 1 in the figure indicates the infrared light proximity sensor, 2 indicates the screen, 3 indicates the frame, a indicates TX, and b indicates RX), which conflicts with the design of the full screen: [0003] The infrared proximity sensor is arranged on the front of the phone, which limits the screen-to-body ratio of the whole phone...
